Weir/waterfall spillway/waterfall blade Construction

[AubreyG]

Has anyone made a weir out of HDPE/acrylic/stainless steel? (That's still around anyway, I emailed koiguy about week ago and haven't heard back)

I’m wanting the water from my elevated bog to spill back into the pond via a waterfall. My bog is a 300 gallon Rubbermaid stock tank so I’m planning on cutting a hole under the rim to attach the spillway via stainless fasteners and silicone.

I figure I can manufacture one easy enough, I just need to know specifics on material thickness? I’d guess that 1/2” HDPE would be enough to withstand the weight. Thoughts on whether acrylic would be the same or thinner/thicker?

I have a welder friend who can fabricate a stainless one, but sometimes I just want to mess around with the heat gun!

Im in the same boat. I emailed him a few weeks ago. This is what I am going to do, unless I find a better solution. I going to buy a waterfall at Lowes, and cut the spillway off of that.

I didn't like the price of the manufactured spillways, so I sort of went and made my own out of a storage container from Lowe's. I simply cut a slot an inch below the lip (so the lid would still fit and I could place a camouflage rock on top that would over hang) and installed a bulkhead fitting and valve to control the amount of flow. And I painted it black so as to hide its composition more easily. Works great. I have two of these. Accessorize with plants and rock and you'd never know Nature didn't put them there...

I’m not wanting a “natural” style waterfall, I’m looking for a clean sheet of water returning.

Besides, I would need a billion dollars worth of rubble stone to hide this sucker that way. Which I don’t want. I’ll be building a cedar “planter” to fit other flower beds in the yard.

This waterfall is plywood, and liner. Will be hidden with stone work.

Is the plywood exposed or covered with the liner?

It is sealed with liner, and covered with stone.
